I have added a new Arc and Sub to my system. The Arc is working fine (like the Playbar before it), but the Sub keeps disconnecting - in the app I then see “Arc +?”.
The Sub is about 1 m from the Arc and around 5 m from the access point. I cannot imagine that the WiFi signal might be too weak, so I have no idea why the Sub keeps disconnecting.
When the Sub is disconnected, sometimes the app asks me if I want to add the sub to the WiFi network, but this usually doesn’t work. The only thing that helps is either rebooting the access point, or unplugging the Sub. Unfortunately, the disconnect happens every 1-2 days, so this is not a solution.
What can I do?
Many thanks in advance!

Note that the SUB connects to the Arc, rather than the signal from your router. It uses a 5Ghz channel, so it may be worth looking at making sure that the radio/wifi is still turned on on your Arc in the Sonos controler’s room settings, and that there aren’t any potential sources of wifi interference that might impact the 5Ghz signal.
The ? is an indication that the SUB isn’t properly connecting, so there’s other things beyond the previous paragraph, and the suggestions from
And I concur with the concern about the access point, in general Sonos doesn’t like those types of things, and most often recommend a wired network setup, where one Sonos device (not a surround or SUB) is wired to the root device of the router. Access points frequently split up networks, and make it hard for Sonos devices to communicate across the split, even though they frequently have the same SSID and password.
